employed or forcing water into a storage rece tacle where it is subjected to air pressure wliich forces it through a system of pipes.

The object of the invention is to provide a pump of this character which will pump the air and the water into the receptacle slmultaneously, and which can be readily adjusted to pump either water alone or both air and water.

With these objects in view my invention consists in certain novel features ofconstruction and incertain parts and combinations' vhereinafter to be described, and then more fully pointed out in the claims.

In the-accompanying drawings, Figure 1 is a side elevation of a complete pump embodying my invention; Fig.v 2 is a vertical section, taken centrally through the lower portion, of such apump; Fig. 3 is a detail sectional view of the discharge pi es and the valve controlling the flow through) the same; Fig. 4 is a transverse sectional view on the line x a: of Fig. 1 andFig. 5 is a sectional de- 'In these drawings, I have illustrated the preferred form of my invention and have shown the samek as embodied in a pump of well known construction, comprising an',u1p

handle 2 and the several parts of the operatling Amechanism are supported and which is providedat a point Intermediate its ends rwith a base 3, which is ada ted to rest upon a supporting platform and) form la support for t e yumpas-a whole. The standard 1 is l prefe'ra Ly hollow and closed at its up er end to' form an ai'rchamber', as hereina ter described. Secured to the lower end of the hollow standard 1 is a housing 4 divided into three compartments, one vof which compartments,.as shown vat 5, is screw-threaded at its upper end to receive the lower end of the hollow standard 1 and is closed at its lower end.

This compartment 5 is `connected atene side which is open at both its top and bottom and is connected at its lower end to the connecting pipe 7 and provided at its u per end with a plunger tube 8 extending in alinement with the connecting pipe'7 and of smaller diameter than said connecting pipe. A

Supported from the connecting pipe is a pumping cylinder 9, rovided with the usual pumping adjunct. his cylinder is preferably of the usual construction, having a valve 10 at the lower end thereof andprovided with a lifting bucket or valved iston,

connected to a pump rod 12 which extends upward through the connecting pipe, chamber 6 and plunger tube 8 to a point near the upper end of theV standard 1, where it is conc nected by any suitable means with the operas consisting of a rack secured to the pump rod 12 and a toothed segment secured to the operating handle 2 and adapted to engage .said rack.

That portion of the pump rod l2, which extendsL through the plunger tube 8, is pro# vided with an inverted bucket or piston 13 passage of water, but to allow the rod a free reciprocating movement therein. This tube maybesecured to the chamber 6 in any suitable manner, but l preferV that herein shown, in whichthe tube is mounted in a plug or cap 14 which is screw-threaded in the upper end of the compartment. The compartment 6 is connected by a passage 15 with a third compartment 16, (see Figs. 3 and 4), which is also open at the top and bottom and is connected at its upper end with a pipe 17 which is provided at its upperl 4end with a discharge spout 18. At its lower end the compartment 16 is connected with a leads to a suitable storage tank. `The flow of water to the pi es 417 and 19 is controlled by means f a dou le faced valve 20, mountwhen in itsv lower position, to closethe pi e 19 and cause the water to ow throu 'h t e llts upper position, to close the pi e 17 and cause the water to flow through t epipe 19 to the storage tank. This valve is provided with asuita le rod 21 which preferably eX- ating handle 2, this means being here shown which serves to close said tube against the.

second discharge pipe 19, which preferably to a compartment 6, (see Figs.l 2 and 4), 55

11', of any suitable construction, w 'ch is 4 ed within the compartment 16 and adapted,

pipe 17 and dischargespout 18, and, w en in tends to a point near the upper end of the standard 1 where it is provided with suitnecting pipe 7 at a point intermediate the cylinder 9 and the housing 4 and is provided with suitable pumping adjuncts. This cylinder may be secured at any suitable point intermediate these two parts and preferably consists of a cylinder similar in most respects to the cylinder 9, save that it is not provided 'with a valve at the lower end thereof, both the inlet and outlet passages being open at all times. This cylinder is preferably provided' at its opposite ends with suitable caps 26 which serve as means for-connecting the cylinder proper with .the end-of the connecting pipe 7. These caps are preferably hollow and form extensions at the opposite ends of the, cylinderf Mounted within the cylinder 25 and secured to the pump rod 12, which extends through the same, is a lifting bucket or -valved piston 27, of any suitable construction, adapted to move in unison with the piston 11 of the cylinder 9.- The` cylinder 25 is provided with a suitableair inlet which preferably consists of a small pi e 28 connected thereto near the bottom `t'he vcylinder, and is hereshown as connected to the bottom cap 26-beyond the limit of movement of the piston. The pipe 28 is provided with f an upwardly extending portion 29, having its upper end extending to a point above the Water level and open to the atmosphere. A

secondpipe 30 is connected to the cylinder 25 `near its upper end, preferably to the up.

per cap 26, beyond the limit of movement of the piston, and is connected at its outer end to the piple 29, thus forming a by-pass connecting t e opposite endsof the air pumping cylinder 25, the by-pass being connectedl with the interior of the cylinder by means of the hollow caps 26. The pipe 29 is provided at its point of union with 'said pipe 30 with a three-way valve 31 connecting the pipes 2 8, 29 and 30 and provided with an operating arm 32, to which is connected a -rod 33 which extends preferably above the supn porting platform and is provided with a suit.-

ablev operating handle 34, by means of which the three wayvalve 31 is turned to connect Q the pipe vv28 either with the air through the upperportion of the ipe 29 Orl-with 'the-up- :per partl of thecylin 'er' 25 throughthe. pipe 30.-" f' suitable checkvaljve' 35, isinterposed between the three wayrvalve 31 in the pipe 28 andthe cylinder 25'. p y

The operation of the device will be readily understood from'the foregoing description. The pump is operated in the usual manner buv-means ofthe handle 2, the pumping cylinder 9 and its pumping adjuncts lifting the Water and forcing the same into the cylinder the bucket 27. erably greater capacity than the cylinder 9,

phere, the bucket 257 will draw in, through the check valve 35, a quantity of air substanof the t'wo cylinders, whichA air is, on the next stroke of the piston, forced through the connecting pipe 7 to the discharge pipe 19 and into thestorage tank. Thus, it will be seen that the operation of the pump in the usual manner serves to pump both air and water into the storage tank at one time. If it is desired to pump water alone, the valve 31 is turned to connect the upper pipe 30 with the pipe 28, thus cutting 0H the air 'which permits that portion of the contents of the cylinder 25 which is in excess of the capacity of the cylinder 9 to circulate through lation of this fluid without in any way interfering `with or impeding the operation of the'pump.. A

I wish it to be, understood ythat I do not construction shown and, described, for obvious modifications will occur to a -person skilled in the art. Y
